en.Wedoany.com Reported - RK International Machine Tools has successfully delivered a new JHC-18S NC1 single-axis centerless grinder from JianDe to a leading European supplier of carbide cutting tools. This delivery not only demonstrates the precision machining capabilities of high-performance machine tools but also highlights the decades-long strategic collaboration strength between RK International and the UK-based diamond tool manufacturer DK Holdings Ltd.
As a star product from Taiwanese manufacturer JianDe, the JHC-18S is renowned for its excellent structural rigidity and high precision. This machine is specifically configured for precision through-feed grinding of carbide blanks. Due to the extremely high hardness of carbide materials, the machining process imposes near-demanding requirements on machine stability and grinding wheel wear resistance. To achieve ideal surface finish and micron-level tolerances, the equipment is equipped with high-performance diamond grinding wheels custom-produced by Kent-based DK Holdings.
The NC1 single-axis configuration adopted by this machine is the core for ensuring consistency in high-volume production. Simon Rood, General Manager of RK International, points out that this configuration allows for precise control of the X-axis feed and enables automatic compensation for grinding wheel wear. This intelligent wear compensation function not only ensures highly consistent part dimensions but also significantly reduces production capacity loss caused by downtime for adjustments. It is a key advantage of modern centerless grinders in high-intensity production environments.

John Emptage, Sales Director at DK Holdings, emphasizes that the combination of the precision machine tool platform provided by RK International and DK Holdings' advanced superabrasive technology offers customers a fully customized, closed-loop solution. This deep cross-industry synergy enables global manufacturers to achieve optimized and repeatable grinding results even when dealing with challenging materials like carbide, ceramics, or hardened steel. This project not only solidifies the position of both UK companies in the high-end manufacturing supply chain but also reaffirms the irreplaceable role of centerless grinders in the production of precision cutting tool blanks.
